    A possible method would be to find the equation of the line on which they must all lie.

    Find the gradient of the line on which all the points lie with the first two points and then equate this to the gradient formula with the last two points (ie. including the one with k in it).

    Try to find an equation of the line and then enter in 4 for x and find k.

    The required area is the integral of 4+ 5x/3- x^/6 between x=0 and the x coordinate at the point the curve crosses the y axis takeaway the area of the triangle formed by the straight line.
